In triangle pqr, rs=4 and qs=6. find ps
Svetradugi [14.3K]

Answer:

PS=2\sqrt{6}

Step-by-step explanation:

we are given triangle as

we know that

triangle PRS and triangle PQS are similar

so, the ratios of their sides must be equal

we get

\frac{RS}{PS}=\frac{PS}{QS}

now, we are given

RS=4

QS=6

we can plug it

\frac{4}{PS}=\frac{PS}{6}

PS^2=6\times 4

PS^2=24

now, we can solve for PS

PS=2\sqrt{6}

Solve each system of equations by substitution. <br> 2x + 2y = 3 x - 4y = -1
Shtirlitz [24]

Step-by-step explanation:

2x + 2y = 3 ( x2 for everything in the equation)

x - 4y = -1

4x+ 4y = 6

x - 4y = -1

Add the 1st line to the 2nd line to get rid of the y:

5x = 5

x - 4y = -1  ( you can pick any line from this system to be the second equation in this step, you can put 2x + 2y = 3 or 4x+ 4y = 6, anything above this step, but to make it simple chose the one you think is the easiest)

Solve for x, then plug the x value into the 2nd equation

x = 1

1 - 4y = -1

x = 1

-4y = -2 =) y = 1/2

x = 1

y= 1/2
